Abstract
Climate-smart sustainable management of agricultural soil is critical to improve soil health, enhance food and water security, contribute to climate change mitigation and adaptation, biodiversity preservation, and improve human health and wellbeing. The European Joint Programme for Soil (EJP SOIL) started in 2020 with the aim to significantly improve soil management knowledge and create a sustainable and integrated European soil research system. EJP SOIL involves more than 350 scientists across 24 Countries and has been addressing multiple aspects associated with soil management across different European agroecosystems. This study summarizes the key findings of stakeholder consultations conducted at the national level across 20 countries with the aim to identify important barriers and challenges currently affecting soil knowledge but also assess opportunities to overcome these obstacles. Our findings demonstrate that there is significant room for improvement in terms of knowledge production, dissemination and adoption. Among the most important barriers identified by consulted stakeholders are technical, political, social and economic obstacles, which strongly limit the development and full exploitation of the outcomes of soil research. The main soil challenge across consulted member states remains to improve soil organic matter and peat soil conservation while soil water storage capacity is a key challenge in Southern Europe. Findings from this study clearly suggest that going forward climate-smart sustainable soil management will benefit from (1) increases in research funding, (2) the maintenance and valorisation of long-term (field) experiments, (3) the creation of knowledge sharing networks and interlinked national and European infrastructures, and (4) the development of regionally-tailored soil management strategies. All the above-mentioned interventions can contribute to the creation of healthy, resilient and sustainable soil ecosystems across Europe.

Abstract
Massive sequencing of fungal communities showed that climatic factors, followed by edaphic and spatial variables, are feasible predictors of fungal richness and community composition. This study, based on a long-term field experiment with tillage and no-tillage management since 1995 and with a crop rotation introduced in 2009, confirmed that tillage practices shape soil properties and impact soil fungal communities. Results highlighted higher biodiversity of saprotrophic fungi in soil sites with low disturbance and an inverse correlation between the biodiversity of ectomycorrhizal and saprotrophic fungi. We speculated how their mutual exclusion could be due to a substrate-mediated niche partitioning or by space segregation. Moreover, where the soil was ploughed, the species were evenly distributed. There was higher spatial variability in the absence of ploughing, with fungal taxa distributed according to a small-scale pattern, corresponding to micro-niches that probably remained undisturbed and heterogeneously distributed. Many differentially represented OTUs in all the conditions investigated were unidentified species or OTUs matching at high taxa level (i.e., phylum, class, order). Among the fungi with key roles in all the investigated conditions, there were several yeast species known to have pronounced endemism in soil and are also largely unidentified. In addition to yeasts, other fungal species emerged as either indicator of a kind of management or as strongly associated with a specific condition. Plant residues played a substantial role in defining the assortment of species.

Abstract
Simulation models represent soil organic carbon (SOC) dynamics in global carbon (C) cycle scenarios to support climate-change studies. It is imperative to increase confidence in long-term predictions of SOC dynamics by reducing the uncertainty in model estimates. We evaluated SOC simulated from an ensemble of 26 process-based C models by comparing simulations to experimental data from seven long-term bare-fallow (vegetation-free) plots at six sites: Denmark (two sites), France, Russia, Sweden and the United Kingdom. The decay of SOC in these plots has been monitored for decades since the last inputs of plant material, providing the opportunity to test decomposition without the continuous input of new organic material. The models were run independently over multi-year simulation periods (from 28 to 80 years) in a blind test with no calibration (Bln) and with the following three calibration scenarios, each providing different levels of information and/or allowing different levels of model fitting: (a) calibrating decomposition parameters separately at each experimental site (Spe); (b) using a generic, knowledge-based, parameterization applicable in the Central European region (Gen); and (c) using a combination of both (a) and (b) strategies (Mix). We addressed uncertainties from different modelling approaches with or without spin-up initialization of SOC. Changes in the multi-model median (MMM) of SOC were used as descriptors of the ensemble performance. On average across sites, Gen proved adequate in describing changes in SOC, with MMM equal to average SOC (and standard deviation) of 39.2 (±15.5) Mg C/ha compared to the observed mean of 36.0 (±19.7) Mg C/ha (last observed year), indicating sufficiently reliable SOC estimates. Moving to Mix (37.5 ± 16.7 Mg C/ha) and Spe (36.8 ± 19.8 Mg C/ha) provided only marginal gains in accuracy, but modellers would need to apply more knowledge and a greater calibration effort than in Gen, thereby limiting the wider applicability of models.

Abstract
Objective: To systematically review the literature addressing the focused question: What is the effectiveness of different surgical and nonsurgical procedures combined with enamel matrix derivative (EMD) on clinical, radiographic, and patient-centered outcomes in intraosseous defects? Methods: Electronic (Medline, Scopus, and Cochrane databases) and hand literature searches were performed for studies including at least 1 treatment arm where EMD had been applied according to 1 of the following procedures: modified Widman flap; papilla preservation variants (PPVs), including papilla preservation technique, modified papilla preservation technique, and simplified papilla preservation technique; minimally invasive variants, including minimally invasive surgical approach and minimally invasive surgical technique; single-flap variants (SFVs), including single-flap approach and modified minimally invasive surgical technique; or nonsurgical application (flapless approach). Data from 42 selected articles were used to perform a network meta-analysis, and a hierarchy of surgical and nonsurgical applications of EMD was built separately for EMD and EMD + graft based on 6- to 12-mo clinical and radiographic outcomes. Results: Among surgical approaches, EMD was associated with best regenerative outcomes when applied through SFVs, with a mean clinical attachment level gain of 3.93 mm and a reduction in the intrabony component of the defect of 3.35 mm. For EMD + graft, limited differences in regenerative outcomes were observed among surgical procedures. PPVs were associated with the highest residual probing depth for EMD (4.08 mm) and EMD + graft (4.32 mm). Conclusions: In the treatment of periodontal intraosseous defects, 1) SFVs appear to optimize the regenerative outcomes of EMD; 2) substantial regenerative outcomes can be obtained with SFVs and conservative double flaps (i.e., PPVs and minimally invasive variants) when EMD is combined with a graft; and 3) residual probing depth was higher following PPVs for EMD and EMD + graft. Knowledge Transfer Statement: The results of the present systematic review and meta-analysis can be used by clinicians to identify the most effective surgical or nonsurgical procedure to treat an intraosseous defect with EMD or EMD + graft. The main findings indicate that when EMD application is indicated, surgical access based on a single flap seems the most appropriate to optimize clinical outcomes. The application of EMD + graft can be effectively combined with single flaps and conservative double flaps.

Abstract
Thyroid ultrasonography (US) is the gold standard for thyroid imaging and its widespread use is due to an optimal spatial resolution for superficial anatomic structures, a low cost and the lack of health risks. Thyroid US is a pivotal tool for the diagnosis and follow-up of autoimmune thyroid diseases, for assessing nodule size and echostructure and defining the risk of malignancy in thyroid nodules. The main limitation of US is the poor reproducibility, due to the variable experience of the operators and the different performance and settings of the equipments. Aim of this consensus statement is to standardize the report of thyroid US through the definition of common minimum requirements and a correct terminology. US patterns of autoimmune thyroid diseases are defined. US signs of malignancy in thyroid nodules are classified and scored in each nodule. We also propose a simplified nodule risk stratification, based on the predictive value of each US sign, classified and scored according to the strength of association with malignancy, but also to the estimated reproducibility among different operators.

Abstract
Biogeochemical simulation models are important tools for describing and quantifying the contribution of agricultural systems to C sequestration and GHG source/sink status. The abundance of simulation tools developed over recent decades, however, creates a difficulty because predictions from different models show large variability. Discrepancies between the conclusions of different modelling studies are often ascribed to differences in the physical and biogeochemical processes incorporated in equations of C and N cycles and their interactions. Here we review the literature to determine the state-of-the-art in modelling agricultural (crop and grassland) systems. In order to carry out this study, we selected the range of biogeochemical models used by the CN-MIP consortium of FACCE-JPI (http://www.faccejpi.com): APSIM, CERES-EGC, DayCent, DNDC, DSSAT, EPIC, PaSim, RothC and STICS. In our analysis, these models were assessed for the quality and comprehensiveness of underlying processes related to pedo-climatic conditions and management practices, but also with respect to time and space of application, and for their accuracy in multiple contexts. Overall, it emerged that there is a possible impact of ill-defined pedo-climatic conditions in the unsatisfactory performance of the models (46.2%), followed by limitations in the algorithms simulating the effects of management practices (33.1%). The multiplicity of scales in both time and space is a fundamental feature, which explains the remaining weaknesses (i.e. 20.7%). Innovative aspects have been identified for future development of C and N models. They include the explicit representation of soil microbial biomass to drive soil organic matter turnover, the effect of N shortage on SOM decomposition, the improvements related to the production and consumption of gases and an adequate simulations of gas transport in soil. On these bases, the assessment of trends and gaps in the modelling approaches currently employed to represent biogeochemical cycles in crop and grassland systems appears an essential step for future research.

Abstract
Acetylcholinesterase (AChE) inhibitors still comprise the majority of the marketed drugs for Alzheimer's disease (AD). The structural arrangement of the enzyme, which features a narrow gorge that separates the catalytic and peripheral anionic subsites (CAS and PAS, respectively), inspired the development of bivalent ligands that are able to bind and block the catalytic activity of the CAS as well as the role of the PAS in beta amyloid (Aβ) fibrillogenesis. With the aim of discovering novel AChE dual binders with improved drug-likeness, homo- and heterodimers containing 2H-chromen-2-one building blocks were developed. By exploring diverse linkages of neutral and protonatable amino moieties through aliphatic spacers of different length, a nanomolar bivalent AChE inhibitor was identified (3-[2-({4-[(dimethylamino)methyl]-2-oxo-2H-chromen-7-yl}oxy)ethoxy]-6,7-dimethoxy-2H-chromen-2-one (6 d), IC50 =59 nm) from originally weakly active fragments. To assess the potential against AD, the disease-related biological properties of 6 d were investigated. It performed mixed-type AChE enzyme kinetics (inhibition constant Ki =68 nm) and inhibited Aβ self-aggregation. Moreover, it displayed an outstanding ability to protect SH-SY5Y cells from Aβ1-42 damage.

Abstract
Evidence indicates that incisor crown form correlates with clinical periodontal features. It was hypothesized that incisor crown form may explain subject differences in gingivitis expression. The present experimental gingivitis study aimed to assess the effect of incisor crown form on plaque accumulation and gingival inflammation, and on individual susceptibility to plaque-induced gingivitis. Eighty-five periodontally healthy subjects were evaluated. A negative correlation was found between incisor crown width/crown length ratio and bleeding score (p = 0.045). From the 85 subjects, two groups of subjects with either ‘long-narrow’ or ‘short-wide’ incisor form were identified. The ‘long-narrow’ group had a significantly higher bleeding score than the ‘short-wide’ group (p = 0.014). No significant differences were found in the incisor crown width/crown length ratio between previously identified ‘high responder’ and ‘low responder’ subjects ( Trombelli et al., 2004a ). In conclusion, incisor crown form appears to affect the bleeding response of inflamed gingival tissues, while it exerts no influence on explaining differences in individuals’ susceptibility to plaque-induced gingivitis.

Abstract
The need for developing real disease-modifying drugs against neurodegenerative syndromes, particularly Alzheimer’s disease (AD), shifted research towards reliable drug discovery strategies to unveil clinical candidates with higher therapeutic efficacy than single-targeting drugs. By following the multi-target approach, we designed and synthesized a novel class of dual acetylcholinesterase (AChE)-monoamine oxidase B (MAO-B) inhibitors through the decoration of the 2H-chromen-2-one skeleton. Compounds bearing a propargylamine moiety at position 3 displayed the highest in vitro inhibitory activities against MAO-B. Within this series, derivative 3h emerged as the most interesting hit compound, being a moderate AChE inhibitor (IC50 = 8.99 µM) and a potent and selective MAO-B inhibitor (IC50 = 2.8 nM). Preliminary studies in human neuroblastoma SH-SY5Y cell lines demonstrated its low cytotoxicity and disclosed a promising neuroprotective effect at low doses (0.1 µM) under oxidative stress conditions promoted by two mitochondrial toxins (oligomycin-A and rotenone). In a Madin-Darby canine kidney (MDCK)II-MDR1 cell-based transport study, Compound 3h was able to permeate the BBB-mimicking monolayer and did not result in a glycoprotein-p (P-gp) substrate, showing an efflux ratio = 0.96, close to that of diazepam.

Abstract
An individual variation in the gingival inflammatory response to the dental biofilm has been demonstrated. This variability can be observed between individuals with neither quantitative nor qualitative differences in plaque accumulation. The reported significant differences in gingival inflammatory response under quantitatively and/or qualitatively almost identical bacterial challenge suggest that the gingival response to plaque accumulation may be an individual trait, possibly genetic in origin. The most recent classification of periodontal diseases acknowledges that the clinical expression of plaque-induced gingival inflammation can be substantially modified by systemic factors, either inherent to the host or related to environmental influences. The aim of the present literature review is to describe (i) the factors influencing the development of plaque-induced gingivitis as well as (ii) those metabolic, environmental and systemic factors which have a direct impact on the etiopathogenetic pathway of plaque-induced gingivitis, thus altering the nature or course of the gingival inflammatory response to dental biofilm.

Abstract
AIM To evaluate the efficacy of triclosan (T)-based toothpaste formulations in the prevention and treatment of plaque-induced periodontal and peri-implant diseases. METHODS A review of the existing literature was conducted with a systematic approach in order to retrieve pertinent articles. RESULTS AND CONCLUSIONS i) Compared with a control fluoride dentifrice, a fluoride dentifrice containing T formulations provides a more effective level of plaque control and gingival health in patients affected by gingivitis; ii) 0.3% T/2% copolymer/0.243% NaF formulation and 0.3% T/0.13% Ca glicerophosphate/1000 ppm F toothpaste in a natural Ca carbonate base seem the most effective T-based toothpaste formulations in controlling plaque and gingival inflammation in patients with gingivitis or mild/moderate periodontitis over a 6-month period; iii) 0.3% T/2% copolymer/0.243% NaF toothpaste formulation can reduce clinical attachment loss in young adolescents when compared with a 0.243% NaF toothpaste formulation, the magnitude of the difference being greater for patients with deep periodontal pockets at baseline; iv) 0.3% T/2% copolymer/0.243% NaF toothpaste formulation is either similarly or more efficacious in preventing the progression/recurrence of periodontal destruction when compared to a conventional fluoride toothpaste; v) 0.3% T/2% copolymer/0.243% NaF toothpaste formulation seems to be more effective than a fluoride toothpaste formulation in controlling the severity of mucosal inflammation, the incidence of mucosal bleeding as well as reducing probing pocket depth around dental implants.

Abstract
PURPOSE This study was undertaken to prospectively determine the diagnostic capabilities of magnetic resonance (MR) imaging in detecting myometrial and cervical invasion and lymph node involvement in endometrial carcinoma and to identify the causes of errors in staging endometrial carcinoma. MATERIALS AND METHODS Twenty consecutive patients with a histological diagnosis of endometrial carcinoma underwent preoperative MR imaging. MR findings were compared with surgical staging, considered as the standard of reference. RESULTS In assessing myometrial invasion, MR imaging showed 70% accuracy, 80% sensitivity, 40% specificity, 80% positive predictive value (PPV), and 40% negative predictive value (NPV). In detecting cervical invasion, MR imaging had 95% accuracy, 100% sensitivity, 94.4% specificity, 66.7% PPV, and 100% NPV. In evaluating lymph node involvement, MR imaging showed 100% accuracy, sensitivity, specificity, PPV and NPV. Errors in evaluating myometrial invasion were caused by polypoid tumour, adenomyosis and leiomyomas, whereas those in evaluating cervical invasion were caused by dilatation and curettage. CONCLUSIONS MR imaging is a reliable technique for preoperative evaluation of endometrial carcinoma. Its main limitation is differentiating between stage IA and IB carcinomas, which is not highly important for surgical planning. Cooperation between the gynaecologist and radiologist is mandatory to avoid staging errors.

Abstract
PURPOSE This study prospectively compared the diagnostic capabilities of magnetic resonance (MR) imaging with conventional defecography (CD) in outlet obstruction syndrome. MATERIALS AND METHODS Nineteen consecutive patients with clinical symptoms of outlet obstruction underwent pelvic MR examination. The MR imaging protocol included static T2-weighted fast spin-echo (FSE) images in the sagittal, axial and coronal planes; dynamic midsagittal T2-weighted single-shot (SS)-FSE and fast imaging employing steady-state acquisition (FIESTA) cine images during contraction, rest, straining and defecation. MR images (including and then excluding the evacuation phase) were compared with CD, which is considered the reference standard. RESULTS Comparison between CD and MR with evacuation phase (MRWEP) showed no significant differences in sphincter hypotonia, dyssynergia, rectocele or rectal prolapse and significant differences in descending perineum. Comparison between CD and MR without evacuation phase (MRWOEP) showed no significant differences in sphincter hypotonia, dyssynergia or enterocele but significant differences in rectocele, rectal prolapse and descending perineum. Comparison between MRWEP and MRWOEP showed no significant differences in sphincter hypotonia, dyssynergia, enterocele or descending perineum but significant differences in rectocele, rectal prolapse, peritoneocele, cervical cystoptosis and hysteroptosis. CONCLUSIONS MR imaging provides morphological and functional study of pelvic floor structures and may offer an imaging tool complementary to CD in multicompartment evaluation of the pelvis. An evacuation phase is mandatory.

Abstract
The present study evaluated human primary osteoblasts and two different osteoblast-like cell lines behaviour when cultured in presence of different hydroxyapatite-based (HA) biomaterials (SINTlife-FIN-CERAMICA S.p.a., Faenza, Italy; Bio-Oss, Geistlich Biomaterials, Woulhusen, Switzerland; Biostite-GABA Vebas, San Giuliano Milanese, MI, Italy), focusing attention on the effect of HA/Biostite in terms of modulation of osteoblastic differentiation. Analysis were about adhesion, proliferation and mineralization activity. Runt-related transcription factor 2 (Runx2), Estrogen Receptor alpha (ERalfa) expression and alkaline phosphatase activity (ALP) were measured as osteoblastic differentiation markers. Determination of viable cells was done with MTT colorimetric assay. Scanning electron microscopy (SEM) analysis was performed on biomaterial-treated cells. All hydroxyapatite-based biomaterials didn't affect cells morphology and viability, whereas only presence of HA/Biostite improved cells adhesion, growth and differentiation. Adhesion and spreading of the primary cells on HA/Biostite were the same showed by two different osteoblast-like cell lines. These results have important implications for both tissue-engineered bone grafts and enhancement of HA implants performance, to develop new teeth's supporting structure therapies and replacement.

Abstract
AIM Cigarette smoking is a risk factor for periodontitis incidence and progression. Contrasting results were obtained when the impact of cigarette smoking on the clinical outcomes of non-surgical periodontal therapy (NSPT) was evaluated. The present study was designed to evaluate the smoking status as outcome determinant of NSPT. METHODS Two groups of patients with different smoking status (smoker group, S, and non-smoker group, NS) were retrospectively selected from a pool of patients seeking care for periodontitis. The effectiveness of NSPT was assessed by evaluating the changes in 1) the prevalence of sites with different pocket probing depth (PPD), and 2) the patient- and site-specific bleeding. RESULTS Group S comprised of 65 patients (mean age: 45.6+/-8.7 years; 24 males and 41 females) and group NS comprised of 66 patients (mean age: 46.8+/-11.7 years; 17 males and 49 females). A statistically significant increase in the prevalence of sites with PPD< or =3 mm (P<0.000), as well as a significant decrease in the prevalence of sites with PPD 4/6 mm (P<0.000) and PPD> or =7 mm (P< or =0.01) was detected at re-evaluation. BoP scores were significantly reduced for the entire dentition (P<0.000) as well as for sites with PPD< or =3 mm (P<0.01) and PPD 4/6 mm (P<0.000) in both group S and group NS. No statistically significant differences in the post treatment change of PPD and BoP scores were detected between groups. CONCLUSION Our results seem to suggest that smoking status has a limited, if any, effect on the clinical outcomes of NSPT.

Abstract
INTRODUCTION This paper reports data from a cognitive survey on the diffusion, practice and organization of ultrasound (US) in emergency medicine departments (EMDs) in Italy. The study was carried out by the Emergency Medicine Section of the Italian Society for Ultrasound in Medicine and Biology (SIUMB) in collaboration with the Italian Society for Emergency Medicine and Urgent Care (SIMEU). METHODS We created a questionnaire with 10 items, relating to 4 thematic areas. The questionnaires were administered from September 2007 to February 2008, by email, telephone or regular mail. In August 2008 the data were subjected to nonparametric statistical analysis (Spearman's Rho and Pearson's chi-square - software SPSS). RESULTS We analyzed 170 questionnaires from the EMDs of all Italian regions. A US scanner is present in 64.7% of the ERs, emergency US (E-US) is practiced only in 47.6% of the ERs, and only in 24% of these more than 60% of the ER team members have training in US. The diffusion of US in other operative units of the EMDs ranges from 8.2% to 26.5%. DISCUSSION The presence of a US scanner in the ER is essential for the practice and training and is correlated with the level of the EMD. The use of US appears to be less common in less equipped hospitals, regardless of the size of the ER and the availability of radiological services. Wider diffusion of US and greater integration with other services for the installment of the required equipment is to be hoped for.

Abstract
AIM Risk assessment is increasingly important in periodontology. The aim of this article was to propose a new objective method (UniFe) in order to simplify the risk assessment procedures. UniFe was compared with a computer-based risk assessment tool (PAT(R)). METHODS Risk scores for both UniFe and PAT(R) were calculated for 107 patients, randomly selected among patients seeking care at a specialist periodontal clinic. For UniFe risk calculation, the ''parameter scores'' assigned to smoking status, diabetic status, number of sites with probing depth 5 mm, bleeding on probing score (BoP) and bone loss/age, were added and the sum was referred to a ''risk score'', ranging from 1 (low risk) to 5 (high risk). PAT(R) generated a risk score on a scale from 1 (lowest risk) to 5 (highest risk). RESULTS The mean UniFe and PAT(R) risk scores were 4.5+/-0.9 and 4.6+/-0.7, respectively. Cohen k-statistics amounted to 0.7, suggesting a good agreement between methods. Difference in risk score between methods was significantly explained by the parameter scores of BoP and bone loss/age (adjusted R2=0.378). CONCLUSION The comparison between UniFe and PAT(R) demonstrated a good level of agreement between methods in a randomly selected population referred to a periodontal clinic.

Abstract
AIM The bacterial colonization of teeth by Streptococcus mutans (StrepM) represents a major risk factor for the development of dental caries. At present, no clinical studies have explored the effect of a combined mechanical-chemical antisepsis protocol in a periodontally-healthy population and the pattern of recolonization of StrepM in subjects whose StrepM infection was successfully eradicated. The present study was designed in order to 1) determine the salivary and plaque changes in StrepM content after a combined mechanical/chemical antisepsis protocol; and 2) evaluate the pattern of recolonization when StrepM was successfully eradicated from saliva and plaque. METHODS Thirty-five periodontally-healthy and caries-susceptible subjects successfully entered and concluded the study. At baseline, non-surgical periodontal therapy was performed according to the principles of full mouth disinfection. Adjunctive home-based rinsing with a 0.2% chlorhexidine mouthrinse was requested for the following week. StrepM concentration was assessed in saliva and plaque at the initial contact appointment, at baseline, and 1-week, 1-month, 3-month and 6-month follow-up. RESULTS A significant effect of ''time'' on StrepM concentration in saliva and plaque was observed (P<0.000). In subjects with successful eradication of StrepM at 1 week (N=17 plaque samples), StrepM infection recurrence occurred within 3-6 months. CONCLUSION The results of the present study demonstrated that 1) the application of the investigated mechanical/chemical antisepsis protocol can effectively reduce StrepM colonies in saliva and plaque of periodontally healthy subjects; and 2) in plaque samples, StrepM infection recurrence tends to occur within 3-6 months.

Abstract
PURPOSE The aim of this study was to evaluate the accuracy of contrast-enhanced colour-Doppler ultrasound (CDUS) in the diagnosis of gastro-oesophageal reflux in children. MATERIALS AND METHODS One hundred and twenty children (68 boys and 52 girls aged between 1 month and two years) with a clinical suspicion of gastro-oesophageal reflux (postprandial vomiting, weight loss, failure to thrive, anaemia, night-time coughing and crying, regurgitation, etc.) were studied by contrast-enhanced CDUS and subsequently by 24-hour pH-metry. Results of the two techniques were compared using the McNemar test. RESULTS Gastro-oesophageal reflux was detected on CDUS in 84 patients and with 24-h pH-metry in 86. In all cases of reflux, CDUS visualised the passage of contrast material from the stomach into the abdominal and middle and distal third of the thoracic oesophagus, enabling assessment of the segment of oesophagus involved by the reflux. Compared with pH-metry, CDUS had a sensitivity of 98% (p<0.0001 with McNemar's test). CONCLUSIONS In consideration of the results obtained and particularly of the low level of invasiveness, contrast-enhanced CDUS could be used to monitor children undergoing medical or surgical treatment for the complications of gastro-oesophageal reflux disease.

Abstract
The paper describes the case of a 25 year-old caucasian man whose cheilitis was initially erroneously diagnosed and treated as herpetic cheilitis, and was then correctly identified as a toothpaste allergic contact cheilitis. The remission of the pathology was achieved through the elimination of the allergen, while the clinical symptoms were controlled by means of topic application of corticosteroids, with a complete and stable restitutio ad integrum of the perioral tissues.

Abstract
PURPOSE Power Doppler ultrasound (US) with time-intensity curves was used to study renal graft function both in the absence of disease and with complications (acute tubular necrosis and chronic rejection) in an attempt to identify pathognomonic patterns. Time-intensity curves allow representation of the kidneys' wash-in and wash-out phases after intravenous administration of sonographic contrast material. MATERIALS AND METHODS Fifty-six asymptomatic renal transplant patients (36 men and 20 women), 19 of whom had altered creatinine clearance levels, were studied by power Doppler US with time-intensity curves followed by biopsy. Ten asymptomatic patients with normal creatinine clearance levels were used as controls. RESULTS Time-intensity curve analysis enabled identification of three groups of patients: group A, consisting of 27 patients showing peak enhancement between 50 and 65 s from intravenous administration of contrast material; group B, consisting of 16 patients with peak enhancement between 135 and 235 s; group C, consisting of three patients with peak enhancement between 100 and 130 s. CONCLUSIONS Data showed significant variations according to renal graft function (no abnormality, acute tubular necrosis or chronic rejection). Although confirmation by a larger series is required, our findings appear to indicate pathognomonic patterns in patients with chronic rejection and acute tubular necrosis.

Abstract
PURPOSE The aim of this study was to evaluate the study of intra- and extra-biliary ducts by contrast-enhanced colour-Doppler in patients who have undergone laparoscopic cholecystectomy. MATERIALS AND METHODS Contrast-enhanced colour-Doppler US was performed in 15 patients who had undegone laparoscopic cholecystectomy. The US contrast agent was introducted into the Kehr or Pedinelli tube to allow visualisation of the bile ducts and duodenum. RESULTS The colour-Doppler study enabled visualisation of the contrat agent in the intra- and extra-hepatic bile ducts and in the duodenum in all patients, thereby permitting the accurate study of the post-operative course. The data obtained were confirmed by conventional radiology. CONCLUSIONS The advantages of this US ultrasound technique are the complete absence of ionising radiation and no intolerance to the US contrast agent. This technique could therefore be used in selected patients as an alternative to trans-Kehr and trans-Pedinelli cholangyography.

Abstract
The TELEMAC project brings new methodologies from the Information and Science Technologies field to the world of water treatment. TELEMAC offers an advanced remote management system which adapts to most of the anaerobic wastewater treatment plants that do not benefit from a local expert in wastewater treatment. The TELEMAC system takes advantage of new sensors to better monitor the process dynamics and to run automatic controllers that stabilise the treatment plant, meet the depollution requirements and provide a biogas quality suitable for cogeneration. If the automatic system detects a failure which cannot be solved automatically or locally by a technician, then an expert from the TELEMAC Control Centre is contacted via the internet and manages the problem.

Abstract
We assessed the accuracy of voiding color Doppler ultrasonography (US) with echo enhancement for diagnosis or exclusion of vesicoureteral reflux (VUR) versus voiding cystourethrography (VCUG) and evaluated patient tolerance of the echo-enhancing agent. One hundred twenty-two patients (ages range, 1 month to 17 years) with 244 ureterorenal units underwent voiding color Doppler US with echo enhancement, which was followed by VCUG on the same day. After US of the urinary tract, the bladder was filled with saline solution via catheter. Then an echo-enhancing agent was instilled, and color Doppler US was performed. Reflux was diagnosed when microbubbles appeared in the ureter or the pelvicaliceal system. VUR was detected in 98 units. All grades of reflux were identified. In 13 units (13.3%), grade I reflux diagnosed at voiding color Doppler US was not observed at VCUG. No reflux was detected in 146 units by either method. In 231 (94.2%) of the 244 ureterorenal units, there was concordance between the two methods. The echo-enhancing agent was well tolerated by all patients. Voiding color Doppler US with echo enhancement is useful for the diagnosis or exclusion of VUR, being as good as VCUG. Therefore, it may reduce the number of patients exposed to ionizing radiation.

Abstract
The objective of this study was to evaluate the usefulness of a galactose-based ultrasonographic contrast agent, Levovist (Schering AG, Berlin, Germany), in differentiating benign from malignant thyroid nodules by analysis of the time-intensity curves correlating the variation of the intensity signal value during the contrast transit time. Fifty-four patients scheduled for surgical removal of a nodule or the thyroid gland or both after cytologic examination were enrolled in this study; all of the nodules underwent a baseline color and power Doppler evaluation and then to a color Doppler examination after an intravenous bolus injection of Levovist. The time-intensity curves were analyzed with respect to the histologic results. Carcinomas showed a significantly earlier arrival time of Levovist than nodular hyperplastic benign nodules and adenomas (8.1 +/- 1.41 versus 19.6 +/- 2.2 and 16.1 +/- 2.8 seconds; P < .0001), although no significant difference occurred between hyperplastic benign nodules and adenomas; carcinomas and adenomas showed an earlier time to peak than hyperplastic benign nodules (14.6 +/- 1.2 and 23.1 +/- 3.8 versus 33.0 +/- 3.0 seconds; P < .0001). No significant difference was found in baseline, peak, final intensity signal, and percent variation of intensity signal among hyperplastic benign nodules, adenomas, and carcinomas. Although cytologic examination still remains the standard of reference for the presurgical diagnosis of thyroid nodules, the preliminary data of this pilot study demonstrate that the analysis of time-intensity curves after Levovist injection might provide useful, complementary, and quantitative information to differentiate benign from malignant thyroid nodules.
